Question

Implement the sum_positive_numbers function, as a recursive function that returns the sum of all positive numbers between the number n received and 1. For example, when n is 3 it should return 1+2+3=6, and when n is 5 it should return 1+2+3+4+5=15.

Answer 1

Answer:

def sum_positive_numbers(n):

if(n==0 or n==1): #if n is 0 or 1 return n as its sum also will be n

return n

return n+sum_positive_numbers(n-1) #else return n and sum of all the number smaller then n

print(sum_positive_numbers(3)) # Should be 6

print(sum_positive_numbers(5)) # Should be 15
